ocamlbuild missing links: using a bash script

ocamlbuild missing links: using a bash script

[Hugo Ferreira]

Hello,

I have a very simple bash script that I use to
build my project using ocamlbuild. The idea is
to build modules successively and execute tests
until compilation fails, a test fails or all
modules are correctly compiled.

It goes something like this:
.................................................
#!/bin/bash

# Exit on error
set -e

ocamlbuild src/comb/tests_comb.d.byte --

ocamlbuild -lib unix src/uf/bench.d.byte --
.................................................

I have noticed however that the build (if
successful) only retains the last symbolic
link to the compiled artefacts.

My questions are:

1. Is the above behaviour intended?
2. If so how can I keep all resulting links

TIA,
Hugo F.

Yes, links made by ocamlbuild are made each time.

If you ask for multiple programs you will get multiple links.

ocamlbuild -lib unix src/comb/tests_comb.d.byte src/uf/bench.d.byte

However it doesn't work in combination with running the given command (using '--').

The  second  option  is  to  forget about this (mis-)feature of links. And use
binaries from the _build dir.
